DESCRIPTION:Activated Random Walks (ARW) is an interacting particle system
  which is believed to be an example of Self-Organised Criticality (SOC)\, 
 in that the competition between the particles' activity and inactivity is 
 expected to spontaneously drive the system to a critical state. In this ta
 lk I will discuss several notions of criticality and\, specialising to ARW
  on the one-dimensional lattice\, I will illustrate how some of them relat
 e to each other. Based on joint work with Lionel Levine (Cornell).
